Who must pay Company Tax?
If your company or association is registered with Companies House, then you must file a Company Tax Return and pay Corporation Tax, even if your business has earned nothing or made a loss. HMRC will send you a ‘notice to deliver a Company Tax Return’ to your registered business address.
When do you file a Company Tax Return?
Your Company Tax Return is always due 12 months after the end of the accounting period it covers. If you miss the tax return deadline, you will have to pay a penalty fine.
The deadline to pay your Corporation Tax bill is usually 9 months and one day after the end of the accounting period covered in your return.
Take control of your Company Taxes
To ensure that you are as prepared as possible to meet your company’s tax deadlines, it is necessary to:
- Keep all evidence of financial transactions, such as receipts and invoices (of income and expenses).
- Use a business bank account, so that all of your company finances are kept in one place.
- Keep an accounting spreadsheet for your business, so that you always have an up-to-date log of your business finances, or hire a professional accountant.
- Consider taking a course in finance to help you understand how to make your business as tax efficient as possible.
- Seek advice from an expert in small business finances.
- Find out about tax deductions which are applicable to your small business. The system of tax deductions is complex and can be confusing at first, but the various reliefs and allowances could end up saving you considerable amounts of money in the long run.
